Hi I hope you staying dry. We have been walking since April one stopping for 2-3 days in major cities on the Camino. It has rained a great deal this year so say many locals. I see people wearing both jackets and pants, and ponchos and pants or gaiters. Both seem to work well. However I would say to wear what covers the top of your boot. People wearing tights and boots or shoes get rain running into the shoe, if it's goretex lined the water does not come out. Recently I'm seeing many who start in Sarria wearing low profile running she's etc. Those are not working at all wet feet and your right blisters and cold feet.
We are wearing rain pants and rain jackets you have to slow down enjoy the rain and walk slowly or you get hot and clammy no matter what your wearing. We are coming to Santiago in a few days. We figured that we had our rain gear on for wind, rain, sleet, or warmth at least 45% of the time.
Buen Camino
